My03 wrx cutting out
 

Hi
Had a problem with the car cutting out, revs dropping when coming to a stand still.
Had codes read which came up as a coil pack error so had that changed. Drove the car again and when coming to stand still revs drop and car cuts out.
There is a check engine light on again but after a obd cable to read it.
Car has previously shown a neutral position sensor but would t hat cause this problem?
Might it be the maf, idle valve or lambda sensor?

what dump valve are you running mate out of interest

Its the standard dump valve

Any ideas anyone?
